BUMPER.

Application filed September 3, 1926.` Serial No. 133,404.

The invention relates to bumpers for automobiles, and has 'for one of its objects to provide a bumper which, while co1npris ing a plurality of vertically spaced impact bars, will permit the insertion of a starting crank between` such bars Withoutany mate rial sacrifice in the strength of the bumper.

Further objects of the `invention will appear hereinafter and will be realized by the construction and arrangement of parts,

sho'vvn in the drawings hereof, wherein Fig. l represents a plan view ci' a bumper constructed in accordance with my invention, the said view showing `portions of the supH portingl arms and of the means for securing thebumper thereto; 2 a front elevation of the bumper shown in Fig. l; Fig. 3 a detail in section corresponding to the line 3-3 ci Fig. 2; and Fig. 4l a detail in section corresponding to the line of Fig. l.

rlhe bumper shown herein comprises a #front orin'ipact section consisting oit a plun rality of vertically spaced front or impact bars, twosuch bars being shown herein and connected at their ends to the ends of coinposite rear or auxiliarypsection, the `bumper being oi the general type shown in patent to McGregorNo. 1,372,154, issued vl-/larch 22,

Describing the various parts by reference characters, l denotes the upper, and 2 the lower, impact barreferred to, each bei' havn .ing its ends curved rearwardly, as indicated at l and E2, respectively, and -each being provided at each end ther-coi with an eye, the eyes on the bar l being indicated. at lb and those on the bar 2 being i'idicated at 2l. yCoopersting with the iront or impact section is the interinediate composite rear or au liary section. This section comprises a pair of. ar members 3, 3, each havingilzs inner end bent inwardly toward the iront or impact bars, as indicated at 2a, and each having at its outer end an eye 3b, which is Y .interposed between the corresponding eyes the said ends 3a being secured to and ibe-l members tween front and rear clamping plGS 6 6a yby means of bolts 7 which extend through the As shown herein, each clamping plate is elliptical in outline andis of suilicient ver-k tical length to enable the plates to engage the front and rear faces of the bars l and 2. Y l

ln audition to the bar members `the rear orfauxiliary section comprises a continuous 'reinforcing bar having ends-S adapted to bear against and tobe secured to the outer portions of the bar members 3 and having a central portion 8a `which is deflected inta vertical direction *soV as tofpermit the starting-.crank to pass through `the center of the bumper. ln the drawing, the central portion 81 is shown as `delected downwardly. 'iilhe ends 8 ot the continuous reinforcing' bar engage the rear 'laces of ther bar members and are secured to suchmembers by means et clampin@` plates 9, 9, and bolts l0" c onn ll in the outer .endsoi thefsaid arms and through the inner ends or" the said clamping plates. .Each oi" these plates has a flange lo at its iront which is adapted to over ,y

hang;` and engage thefront iace ofthe corresimnding bar member 3, and the clamping plates are additionally secured to the 3 and' they parts 8 by means of the bolts 13. i i

'lhe bar 8,- Sa not onlyserves to strengthen the bumper and to compensate. for lach of continuity in the back bar 3, 3a, but also serves to receive the bar 2 and the parts 8 ili'the central portion of the bumper is de- 'lhictedrearwardlyav distancel equalgto or greater than that between the central por tion of the reinforcing bar 8, 8 and the corrcspoinling portions ofthe parts .2 and 3. Should the central portions ot the bars in the Yfront of the part 8 be deflected still further, such :further rearward movement will be resisted by the frictional drag exerted upon the parts 8 by the clamping plates 9, 9 and l0.

It is apparent that the reinforcing bar 8 may be bent upi Yardly at 8L1 instead of downwardly itl such a configuration would be more suitable in the use of the invention.

The xear bar 3, 3 has been shown as made up orA two members connected together by the chimp plates G, G". lt is apparent that these members might bc replaced by a continuous bar having an eye at each end and having its central portion horizontally olflset to avoid the impact bars and vertically offset to provide a space lor the reception of the crank, and it is not intended to limit the invention to the particular embodiment herein shown.
